Price does not change for logged in user on pages they previously visited

[leahRae]

Hello,

When a user is on my site and login after browsing the website the prices do not change on the pages they have visited. It used to. I have 2 types of users regular and wholesale.

I have turned off all the caching and it still does not change. Even if they clear their browser history, they still see the regular price and not the wholesale price.

Joomla 2.5.9
Virtuemart 2.0.18a

Thanks for any assistance!!!
